   <p>当Oracle主机中的环境变量注册表被误删后，导致管理界面上显示主机离线，数据库备份恢复任务失败。</p>
   <div class="section">
    <h4 class="sectiontitle">操作步骤</h4>
    <ol>
     <li><span>请使用系统管理员登录Oracle数据库主机。</span></li>
     <li><span>在键盘上按<span class="uicontrol" id="oracle_gud_0135__oracle_gud_0016_uicontrol11819941114510">“Win+R”</span>，打开运行窗口。</span></li>
     <li><span>输入<span class="parmvalue">“regedit”</span>，打开注册表，检查ORACLE注册内容是否正确，如不正确请修改正确。</span><p></p>

       <div class="notebody">
        <p>其中<span class="parmname">“ORACLE_HOME”</span>的值需增加至系统变量<span class="parmname">“Path”</span>的值中，<span class="parmname">“Path”</span>中该值为<span class="parmname">“ORACLE_HOME”</span>的值加上<span class="parmvalue">“bin”</span>，并用英文分号与其他路径分割。</p>
        <p>例如：</p>
        <p>ORACLE_HOME的值为：C:\app\oracle\product\12.1.0\dbhome_1，则系统变量Path对应值中需要有“C:\app\oracle\product\12.1.0\dbhome_1\bin”。</p>
